Introduction

Texas Instruments (TI) is also building ARM Cortex-M4 processors, this board
has the LM4F232 on it. One of the interesting things about TI’s versions is
that they are more skewed toward the sensor role, building on DSP features
in the Cortex-M4 TI seems to be pointing these offerings at the automotive
market.

From the image you can see the basic layout of this board. Reading through
the User’s Guide can be helpful here. The thing that confused me
initially about this board is that there are two USB connections,
the one on the left is a ‘mini’ USB and the one on the bottom is a ‘micro’
USB connector. The left one connects to a captive Cortex M3 (LM3S3601) which
has a proprietary sort of debug thing going on. The bottom one connects to
the native USB-OTG port of the Stellaris part. In a number of the TI demos
they use the lower one for a serial console.
